Hi guys, new guy having some issues with my mower - probably took on a little more than I should have. I really don't have any small engine experience, but I'm not afraid to get my hands dirty.
There is a bit of background that will probably help figure out what I did, but at this point I can not get the motor to start, the pull cord is difficult to pull and the motor just feels dead - for lack of a better term not like it even wants to to start. The pull cord has been difficult for some time.
Mower is Toro 22" GTS Model 20016 with the Tecumseh LEV 80-120 engine about 9-10 years old poorly maintained
I recently rebuilt the carb a few months ago and I was having an issue of fuel spitting back into the air filter on occasion and engine running poorly - I determined that I likely rebuilt the carb with the needle going the wrong direction and made the correction - the float was new but I double checked it anyway. Engine still ran poorly and I began to get white smoke from the engine after a test run. Did not notice any fuel spitting back into the filter. I did some research and came a across the most likely cause being oil getting into the fuel, I checked the spark plug - less than a year old and found oil on the tip. I decided to drain the oil and gas and replace the gaskets on the carb and the head gasket (about a year ago I pulled the head off and did not replace it). So I ordered the complete gasket kit. Cleaned off the carbon deposits on the inside of the head, piston and valves. (I noticed that the valves did not seat flush with the top but appeared to close completely to the eye), the cylinder appeared to be smooth. The piston did leave a small bit of oil on the cylinder walls which leads me to believe I may need to change the Rings? While doing this I noticed oil stains around the flange - I did not plan on changing this gasket but since it was included it in the kit the "might-as-well" mentality kicked in - this is probably where I went wrong. I opened the housing removed the old gasket, cleaned the housing and re-assembled with the new gasket - the pin from the oil pump came out and the camshaft came out as well. Nothing else inside was pulled. One thing I was not aware of was the timing marks - I know I will have to open it back up and and check those, but the piston and valves closed at the same time so it should not be to far off. New spark plug and air filter. Everything got re-assmebled and there where no left over screws.
I uploaded a PDF of the parts catalog, has the exploded view of the engine on page 10 if it will help.
Thanks in advance any help is most welcome....
